head_content
The
<base>
tag should appear only in the document header, not in its
body contents. The browser thereafter uses the specified base URL, not
the current document's URL, to resolve all relative URLs, including those
found in
<a>
,
<img>
,
<link>
, and
<form>
tags. It also defines the URL that
will be used to resolve queries in searchable documents containing the
<isindex>
tag. [

The
HRef
attribute must have a valid URL as its value, which the browser
then uses to define the absolute URL against which relative URLs are
based within the document.
